The direct-acting proportional valve Type 2822 can be used as a control valve for process control and is suitable for technical vacuum. A special design minimizes frictional and stick-slip effects and provides an excellent span, repeatability and sensitivity. The valve is driven either by DC or by a high frequency PWM signal. With the input signal at zero, it closes tightly owing to an elastomer seatseal. Because of its almost silent operation, the valve is specially suitable for medical applications.
